Abstract [en]

This is a Bachelor Thesis within the subject of system architecture and was written in Swedish. In this thesis, the purpose and deliverables were to investigate and answer the given questions regarding the subject system architecture. The projects purpose is to study the use of DSM and the newly developed research tool IGTA++, a MATLAB based algorithm. Can the mentioned tools be used for modularization of already existing products and can products with high demands on performance and specific areas of use be modularized with the same method are the questions that will be answered.

By choosing three products with different areas of use, demands on performance and precision but also different product architectures and then taking them apart and studying the components and their interactions, the questions were answered. The three chosen products were a pneumatic nutrunner relying heavily on mechanics to fulfill its purpose, a drilling machine using both electronics and mechanics and lastly a haptic unit whose function depend on electronic signals.

Analyzes of the products components resulted in DSM:s for each product. Thereafter the DSM:s were clustered in MATLAB using IGTA++ to obtain suggestions on how the products should be modularized. The suggested modules were analyzed and it was seen that the results are sufficient but require some work to be useful.

The conclusions of the project are that IGTA++ serves as an aiding tool when modularizing but demands post algorithm work to achieve desired results. The algorithm can be applied to different types of product architectures and variations in the results are related to the products complexity. IGTA++ can also be used for already existing products to completely or partially modularize.
